摘要： Systems and methods are disclosed for supporting virtual microengines in a multithreaded processor, such as a microengine running on a network processor. In one embodiment code is written for execution by a plurality of virtual microengines. The code is than compiled and linked for execution on a physical microengine, at which time the physical microengine's threads are assigned to thread groups corresponding to the virtual microengines. Internal next neighbor rings are allocated within the physical microengine to facilitate communication between the thread groups. The code can then be loaded onto the physical microengine and executed, with each thread group executing the code written for its corresponding virtual microengine.

摘要： Method and apparatus to support a large Internet Protocol Forwarding Information Base. A packet is received at a network device, the packet including a destination address. A table is indexed into using a portion of the destination address to locate an entry in the table associated with the portion of the destination address. A pool index is derived from the portion of the destination address and is used to identify a pool of data blocks from among a plurality of pools of data blocks. The entry and the pool of data blocks are navigated to find a next-hop for the packet.

摘要： In general, in one aspect, the disclosure describes a method of tracking a network statistic stored within a collection of bits. The method includes storing the collection of bits storing the network statistic as at least a first portion and a second portion. The first portion includes a set of least-significant bits and the second portion includes a set of more significant bits. The method also includes incrementing the first portion based on a packet and=determining if the incrementing of the first portion caused a designated bit of the first portion to be set. If it is determined that the incrementing of the first portion caused the designated bit to be set, the method increments the value stored by the second portion and resets the designated bit within the first portion.

摘要： In general, in one aspect, the disclosure describes a method that includes at a first packet processing thread executing at a first core, performing a memory read to data shared between packet processing threads including the first thread. The method also includes at the first packet processing thread, determining whether the data returned by the memory read has been changed by a packet processing thread operating on another core before performing an exclusive operation on the shared data by the first packet processing thread.

摘要： A tool that enables a user to perform instruction operand tracing during debug is presented. While executing microcode on a simulator, a history of register and memory values is saved. A graphic user interface uses these values to present a view of the microcode in a thread history. The user can use the thread history to select any given cycle time of the simulation, and switch over to a thread window (or code list view). The instruction that executed at the cycle of interest is marked in the code list view, and right-clicking on the code line, the user is given options, including an option to jump backward in time to the code line where a source variable was set and/or the option to jump forward in time to a code line that used a result variable.

摘要： A scheduling mechanism to control transmission of data units, such as variable size packets or fixed size cells, to ports of a network device such as a switching fabric system. The scheduling mechanism maintains scheduling data structures, including an array storing information for available queues of ports and circular buffers representing nonempty port queues of the available port queues according to classes of service. The scheduling mechanism uses the data structures to make scheduling decisions concerning the scheduling of data units in the nonempty port queues for transmission to the ports.

摘要： In general, in one aspect, the disclosure describes a system to process packets received over a network. The system includes a receive process of at least one thread of a network processor to receive data of packets belonging to different flows. The system also includes a transmit process of at least one thread to transmit packets received by the receive process. A scheduler process of at least one thread populates at least one schedule of flow service based, at least in part, on quality of service characteristics associated with the different flows. The schedule identifies different flow candidates for service. The system also includes a shaper process of at least one thread to select from the candidate flows for service from the at least one schedule.
